る本考案のものとは別異である。 A heat exchanger having a synthetic resin tank as described above has conventionally been constructed as shown in FIG. That is, a large number of liquid passage pipes 1, 1 and fins 2, 2
(In addition to the plate fins shown in the figure, corrugated fins are also widely used as fins.) The upper and lower ends of the core part 3 (only the upper end is shown, but the lower end has the same structure) are made of metal. seat plate 4,
The ends of the fluid pipes 1, 1 are inserted into the holes 5 drilled in the seat plate 4, and the abutting parts of both members 1, 4 are joined by brazing, and the upper surface of the peripheral edge of the seat plate 4 is connected. The flange 7a at the lower end of the synthetic resin tank 7 is placed on the packing 6 placed on top of the packing 6, and the peripheral edge of the flange 7a and the seat plate 4 is compressed elastically between the two members 7a and 4. In this state, they are connected using a restraining tool 8. However, when joining the seat plate 4 and the tank 7 with the structure described above, packing 6 and restraints 8 are required, which not only increases production costs due to an increase in the number of parts, but also requires the use of restraints. Since tightening work is required, the joining work itself becomes troublesome. In addition, as a structure for joining the tank to the seat plate, Japanese Utility Model Publication No. 56-39912 and
There is a device described in Publication No. 55-29311, but in the former, the upper end of a deep seat plate that also serves as the tank body is bent to form a U-shaped groove 14a, and the hem of the cap 1 is fitted into this. However, it requires troublesome work such as caulking and welding, does not use a synthetic resin tank, and has a different structure from that of the present invention described below.

座板を直接結合する構造とは別異である。 The latter is a structure that uses a synthetic resin tank and has an insert plate 15 attached to its bottom (Fig. 5B). This is a device that connects a tank and a seat plate, and as in the present invention described below, a folded wall formed on the periphery of the seat plate is fitted into a groove of the tank in a fluid-tight manner to connect the tank,
This is different from the structure in which the seat plates are directly connected.

ク７の端部に包埋させることにより行なう。 FIG. 2 is a partial vertical sectional view showing an embodiment of a heat exchanger having a synthetic resin tank according to the present invention. 1st
Similar to the conventional heat exchanger shown in the figure, the peripheral edge of the seat plate 4 joined to the ends of the liquid passage pipes 1, 1 of the core part 3 has a folded wall 4a facing in the opposite direction to the core part 3. , are formed over the entire circumference of this seat plate 4. This folding wall 4a has a groove 7b on the end face of the synthetic resin tank 7.
The seat plate 4 and the tank 7 are fluid-tightly joined at this fitting portion. In order to maintain liquid tightness in this fitting part, after fitting the folded wall 4a into the groove 7b formed on the end face of the tank 7, the seat plate 4 is heated by means such as high-frequency induction heating, and the fitting is made. Either the resin on the inner surface of the groove 7b constituting the joint is melted and adhered to the surface of the folding wall 4a, or the tank 7
This is done by embedding the folded wall 4a in the end of the tank 7 when molding it with synthetic resin.

That is, the example of FIG. 3 is an example in which the cross-sectional shape of the folding wall 4a is curved in a waveform in the vertical direction, the example in FIG. 4 is an example in which the cross-sectional shape of the folding wall 4a is wedge-shaped, and the example in FIG.
The example shown in the figure is an example in which a large number of small holes 9, 9 are bored in a folding wall 4a, communicating the front and back sides of this wall 4a, and the synthetic resin that makes up the tank 7 is also allowed to enter into these small holes 9, 9. FIG. 6 shows an example in which the folding wall 4a is curved in a waveform in the lateral direction. Standing wall 4a
By forming the groove part 7b of the tank 7 in this way and tightly fitting the vertical wall 4a, even if a force acts in the direction of separating the tank 7 and the seat plate 4 (due to the internal pressure of the tank 7), , a force in such a direction is applied to the joint between the two members 7 and 4), the joint will not be damaged. In addition, since the synthetic resin that constitutes the tank 7 has a certain degree of elasticity, it can be fitted into the groove 7b even if the cross section of the folded wall 4a is not flat.
Considering the time and effort required to process the groove 7b itself, if the folded wall 4a is formed as shown in Figs. In this case, the seat plate 4 and the tank 7 are joined together, and at the same time, a groove 7b is formed in the end face of the tank 7 into which the folded wall 4a is fitted.
本考案の合成樹脂製タンクを有する熱交換器の
その他の構成については、従来の熱交換器と同様
であるため、説明を省略する。 The rest of the structure of the heat exchanger having a synthetic resin tank according to the present invention is the same as that of a conventional heat exchanger, so a description thereof will be omitted.

の製造を容易にすることができる。 In the heat exchanger having a synthetic resin tank of the present invention, a groove 7b is formed on the end face of the synthetic resin tank, and a folded wall 4a formed directly on the seat plate is fitted and welded into the groove 7b. There is no need for any connecting parts, which simplifies the connection structure between the seat plate and the tank, making the connection work easier. That is, compared to the conventional structure shown in Figure 1, the number of parts is reduced, making it easier to manage parts, and there is no need to perform troublesome caulking work to connect them, making it easier to manufacture the heat exchanger. It can be done.

も不要である。 Furthermore, as in the case described in Japanese Utility Model Publication No. 56-39912, an upward U-shaped groove is formed by complicated folding on the edge of the tank body 14, and the hem of the cap is inserted into this groove, caulked, and welded. There is no need for such troublesome work.
さらに、実開昭55−29311号公報に記載された

べて、作業が容易であり部品数も少なくなる。 Furthermore, compared to the structure described in Japanese Utility Model Publication No. 55-29311, which requires troublesome work such as winding and tightening the seat plate and the insert 15, the work is easier and the parts are easier to work with. The number will also decrease.

て、実用上の効果が大きい。 As described above, the heat exchanger with the synthetic resin tank of the present invention has fewer parts than the heat exchanger with the conventional tank structure described above, which makes parts management easier and requires less troublesome work. It is possible to simplify manufacturing and reduce manufacturing costs by omitting this, which has a great practical effect.
